I'm not a great fan of shots (not counting tequila haha), but if there is one I really like making it and drinking it as well is B-52. It's so fun to make and even funnier to drink. And that's how you do it:
Take your shot glass and fill it 1/3 of cold Kahlua (coffee liquor), than take your table spoon and slowely layer down the Bailey's (Irish Cream liquor). And for the last layer, thera are so so so many options. Me, myself like using cointreau mixed with a bit of schnopps (so it will burn more). And when that's done, you just light up the drink, take you straw and sip it right till the end of the drink and the fire. Be careful, it's gonna be hot!
Enjoy!
